Abstract
The positive effects of photobiomodulation (PBM) on a variety of conditions or illnesses are often reported. Most of these studies focus on local effects: tissue that is directly exposed to red or near-infrared (NIR) light benefits. Our work takes the PBM effect a step further: a double-blind, placebo-controlled clinical study on a group (n=56) of generally healthy people shows significant (p<0.05) positive effects on health and well-being. These systemic (i.e. whole body) effects resulted from only partial exposure of their body (participants were exposed to NIR light with their face and neck only). Different doses were tested to find an optimum in terms of both effectiveness and energy usage, and the study was done in both summer and winter to verify the effect of season. In a world where most people are deprived of natural NIR light, our study shows the importance of NIR light integration in the indoor environment to enhance the health and well-being of people.
